DEVICE FOR LUBRICA'TING CAR-JOURNALS.

SPECIFICATIQN forming part of Letters Patent No. 701,029, dated May 27,1902.

Application filed Augnst S, 1901. Serial No. 70,759. (No-model.)

T ztZZ whmn it may concern:

Be it known that 1, JOHN E. GILL, a citizen of the United States,residing at Franklin, in the county of Venaugo and State of Pennsyl-Vania, have invented certain new and useful Improvements in Devices forLubricating Car-Journals, of which the following is a specification.

My invention relates to improvements in devices for lubricatingcar-journals.

One object of my invention is to provide a device of simpleconstruct-ion for'positively supplying lubricating material to acar-journal which shall be durable, reliable, and easy of access.

Another object of my invention is to provide such a device which shallnot depend upon capillary action for its supply of lubricating fluid.

These and such other objects as may be attained by my invention areillustrated in the accompanying drawings, in which- Figure 1 is ahorizontal section through a car-axle box containing my invention on the1 line 1 1 of Fig. 2 looking in the direction indicated by the arrows.Fig. 2 is a sectional view on the line 2 2 of Fig. 1 looking in thedirection indicated by the arrows. Fig. 3 is a similar View to Fig. 1,showing a modified form of my device. Fig. 4 is a cross-sectional viewon the line 4 4 of Fig. 3 looking in the direction indicated by thearrows. -Fig. 5 is a detail showing a modified form of mylubricating-padsupport. Fig. 6 is an enlarged detail showing theoil-supply inthe modified form of my device, and Fig. 7 is an enlargeddetail showing the application of onefeature of my invention to adifferent form of padsupport.

Like letters of reference indicate the same parts in the several figuresof the drawings.

Referring by letter to the accompanying drawings, A indicates acar-journal box.-

B is the car-journal.

C is a thin metal plate pivotally connected to the inner arms of thepivoted levers D, which extend through the sides of the journal-box andare actuated by the weights E, by means of which the plate 0 is normallyand yieldingly held snugly against the under surface of the car-journalB.

As is more clearly shown in Fig. 5, the

plate 0 is in the form of a shallow tray and is adapted to receive andhold an absorbent pad F against the under surface of the journal.

In the simpler form of my device the pad F is placed in or about thetray C, and the supply of oil is poured directly into the tray 0 andupon the pad F. This supply of oil isrcneWed from time to time by themen having charge of oiling the car-bearings. By virtue of the constantaction of the weights E the pivotal mounting of the levers D andthe'pivotal connection between the lovers D and the plate or tray 0 theoil-pad F is at all times kept snugly in contact with the under surfaceof the journal, directly below the brasses G, thereby insuring apositive and continuous lubrication of the journal-bearing. If desired,

the plate or tray C may be made of extremely thin and flexible metal, inwhich event a pivotal connection between the plate 0 and the levers Dwould not be essential, although I consider the pivoted constructionpreferable.

While my construction as above described is also adapted for use inconnection with wicks which shall extend from the pad F to a supply ofoil in the bottom of the journalbox and shall keep the pad F suppliedwith oil by capill-ary'action, in which event, of course, suitableopenings for such wicks would be provided through the plate 0, I preferto keep my device continuously supplied with oil by means of themodified construction shownrin Figs. 3 to 6, inclusive. In these figuresit will be observed that the plate or tray 0 is provided with extensionsor lips 0. These extensions may be provided on either or both sides ofthe tray and are intended to support corresponding extensions of the padF, although, if desired, the extensions on the pad F may be dispensedwith. These lips c extend beyond the journal B and are designed toreceive oil from oil-inlet ports h, (see Fig. 6,) which connect bysuitable passages with oil-cups H, mounted upon the journal-box at apoint above the under side of the journal. In the simpler embodiment ofthis feature of my invention these oil-cups are mounted directly on thetop of the journal-box, and the oil-inlet, port h opens into thejournal-box immediately above the lips or extension 0, so that as theoil drops from the oil-cups it is received by the extension 0 and flowsthence to the lubricating-pad F. Of course with this construction therate of oil-supply can be regulated in any usual manner.

The device in Fig. 7 is the familiar one of alubricating-pad which issupported against the under surface of the journal by means of a springI. Such a pad as now used is supplied with oil by means of wicksextending from such pad downwardly to an oil-reservoir. Adapting myinvention to a pad of this description the pad is provided with lat eralextensions 0', which may either be extensions on the pad itself or maybe merely laterally-extending devices for receiving the oil as it is fedfrom the oil-cups H and for carrying such oil to the pad 0.

Of course my invention is subject to various modifications in detail.For instance, each of the levers D may be independent of the otherlevers and may be so formed that the outer arm thereof shall act as theweights E. So, also, the exact form, contour, and dimensions of thepad-support C may be varied considerably without departing from thespirit of my invention; but these and similar modifications are allcontemplated by my invention.

While in the simpler embodiment of my invention, as shown in thedrawings, weighted levers are used for holding the lubricatingpad incontact with the journal, I do not wish to be limited to the use ofweighted levers for this purpose, as any suitable means for yieldinglyholding the levers in the desired position may be used.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The combination with a car-journal, of a journal-box, anoil-reservoir, and means for supporting said reservoir adjacent to theunder side of the car-journal, said means comprising a counterweightedlever hinged directly to said reservoir and extending through, andfulcrumed on, one wall of the journal-box, substantially as described.

2. The combination with a car-journal, of a journal-box, anoil-reservoir within said journal-box, and a counterweighted yokecomprising a pair of arms which extend through and are fulcrumed in onewall of the journal-box, the inner ends of said arms being hinged to oneend of the oil-reservoir, substantially as described.

3. The combination with a car-journal, of a lubricating-pad, means foryieldingly hold ing said lubricating-pad against the under surface ofthe car-j ournal, oil-receiving means extending laterally from said padbeyond said car-journal, an oil-cup mounted above said pad, and meansfor supplying oil from said oil-cup directly to said lateral extension,substantially as described.

4:. The combination with a car-journal, of a lubricating-pad, means forholding said lubricating-pad yieldingly against the under surface of thecar-journal, oil-receiving means extending laterally from said padbeyond said journal, and an oil-cup mounted above said pad. whereby oilmay be fed from said oil-cup directly to said oil-receiving means,substantially as described.

5. The combination with a car-journal, of a journal-box, alubricating-pad within said journal-box, means for yieldingly holdingsaid pad against the under surface of said journal, oil-receiving meansextending laterally from said pad beyond said journal, an

oil-cup mounted upon said journal-box and means providinga passageleading from said oil cup to a point within said journal-box, wherebyoil may be dropped from said oilcup directly to said oil-receivingmeans, substantially as described.
